Ternary flip flop pre driver based on ternary and quaternary logic has pnp logic or or dual gate and and p binary and gate and carry signal

摘要

A ternary flip-flop pre-driver (30) based on ternary/quaternary logic comprises a PNP-logic OR-OR dual gate (9), two end stages (17) and a P-binary AND gate (7) and a simultaneous carry signal (C). Four electrical potential levels give logic numbers 0,1,2,3. End stage inputs (A,B) and AND inputs are controlled by OR-OR outputs (Q1,Q2).
